2-(1-Cyano-1-methylethyl)azocarboxamide (CABN) is a representative of new-type azo initiator in the radical polymerization industry. The peculiar water and oil soluble characters make it a versatile rising star for the industry to initiate the polymerization of monomers in either polar or nonpolar solvents based continuous phases. This paper decodes the effect of acylamino and cyan groups on thermal stability and hazards of CABN via advanced thermokinetic analysis and numerical simulation. Initially, simultaneous thermogravimetric analyzer was employed to evaluate the thermal stability of CABN and its two structurally similar azo compounds (azos), azobisisobutyronitrile (AIBN) and azodicarbonamide (AC). Followed with calorimetric experiments by differential scanning calorimetry, the effect of two functional groups on thermal behavior parameters, such as decomposition temperature, melting point, and heat of decomposition was estimated. The results indicated that the acylamino group can improve the thermal stability of CABN but with bulkier heat release. Ultimately, through the medium of thermokinetic analysis, the thermal hazard of AIBN, CABN, and AC was simulated based on auto-ignition and thermal explosion theory. The research results would provide references for the synthesis of new-type azo initiators and process safety parameters to the polymerization industry.

2-（1-氰基-1-甲基乙基）偶氮羧酰胺（CABN）是自由基聚合工业中新型偶氮引发剂的代表。独特的水溶性和油溶性使其成为工业通用的后起之秀，可在基于极性或非极性溶剂的连续相中引发单体聚合。本文通过先进的热动力学分析和数值模拟，对酰基氨基和氰基对CABN热稳定性和危害的影响进行了解释。最初，同时使用热重分析仪评估CABN及其两种结构相似的偶氮化合物（偶氮），偶氮二异丁腈（AIBN）和偶氮二甲酰胺（AC）的热稳定性。接着通过差示扫描量热法进行量热实验，研究两个官能团对热行为参数的影响，估算分解温度，熔点和分解热。结果表明，酰基氨基基团可以改善CABN的热稳定性，但释放热量较大。最终，通过热动力学分析，基于自燃和热爆炸理论模拟了AIBN，CABN和AC的热危害。研究结果可为新型偶氮引发剂的合成和聚合工业的工艺安全性参数提供参考。交流电是根据自燃和热爆炸理论进行模拟的。研究结果可为新型偶氮引发剂的合成和聚合工业的工艺安全性参数提供参考。交流电是根据自燃和热爆炸理论进行模拟的。研究结果可为新型偶氮引发剂的合成和聚合工业的工艺安全性参数提供参考。
